Figure 1: Time series of spawning biomass with scaled spawn indices (top), recruitments (second row), natural mortality (third row), and harvest rates (bottom row) for substocks of SOGHerring. Stocks are, from left to right,SOG.
Figure 2: Probability of detection of a spawning event, with respect to spawning stock biomass. Lines show the modeled probability and the points indicate whether a spawn was detected, with 0 for no spawn detected, and 1 for a positive index.
Figure 3: Average model fits to age data. Stocks are left to right, and gears are top to bottom.
Figure 4: Model fits to age data, averaged over stock and time. Gears are top to bottom.

Figure 5: Age-1 recruitments for all stocks. Equilibrium unfished recruitment \(R_0\) is indicated by the horizontal dashed line. Second row shows recruitment residuals on the log scale, with the average of estimated residuals shown by the horizontal red dashed line.
